ETC HYM71V63M1601TX-75

16x64 bits
PC133 SDRAM SO DIMM
based on 8Mx16 SDRAM with LVTTL, 4 banks & 4K Refresh
HYM71V63M1601 X-Series
DESCRIPTION
The Hyundai HYM71V63M1601 X-Series are 16Mx64bits Synchronous DRAM Modules. The modules are composed of
eight 8Mx16bit CMOS Synchronous DRAMs in 400mil 54pin TSOP-II package and 2Kbit EEPROM in 8pin TSSOP
package on a 144pin glass-epoxy printed circuit board. Two 0.33uF and one 0.1uF decoupling capacitors per each
SDRAM are mounted on the PCB.
The HYM71V63M1601 X-Series are Small Outline Dual In-line Memory Modules suitable for easy interchange and
addition of 128Mbytes memory. The HYM71V63M1601 X-Series are offering fully synchronous operation referenced to a
positive edge of the clock. All inputs and outputs are synchronized with the rising edge of the clock input. The data paths
are internally pipelined to achieve very high bandwidth.
FEATURES
• PC133/PC100MHz support
• SDRAM internal banks : four banks
• 144pin SDRAM SO DIMM
• Module bank : two physical bank

• Auto refresh and self refresh
• 1.25” (31.75mm) Height PCB with Double Sided
components
• 4096 refresh cycles / 64ms
• Single 3.3 ± 0.3V power supply
• All devices pins are compatible with LVTTL interface
• Data mask function by DQM
• Programmable Burst Length and Burst Type
-. 1, 2, 4, 8 or Full Page for Sequential Burst
-. 1, 2, 4 or 8 for Interleave Burst
• Programmable /CAS Latency
-. 2, 3 Clocks
